## Abstract

A bionic animal includes a fore body, a hind body and a tail. The hind body is rotatably connected to the fore body. The tail is connected to the hind body. The tail includes an elastomer, a plurality of joint members and at least one driving wire. The plurality of joint members are disposed side by side on the elastomer. The at least one driving wire passes through the plurality of joint members and is connected to the fore body. When the hind body rotates with respect to the fore body, the at least one driving wire is pulled to drive the plurality of joint members to rotate with respect to each other, so as to drive the elastomer to elastically deform. After the at least one driving wire is released, the elastomer provides an elastic force to make the plurality of joint members return.

## Claims

### Claim 1

A bionic animal comprising:
a fore body;
a hind body rotatably connected to the fore body; and
a tail connected to the hind body, the tail comprising:
an elastomer;
a plurality of joint members disposed side by side on the elastomer; and
at least one driving wire passing through the plurality of joint members and connected to the fore body;
wherein, when the hind body rotates with respect to the fore body, the at least one driving wire is pulled to drive the plurality of joint members to rotate with respect to each other, so as to drive the elastomer to elastically deform; after the at least one driving wire is released, the elastomer provides an elastic force to make the plurality of joint members return;
wherein the hind body comprises a first rotating member rotatably connected to the fore body; and a second rotating member rotatably connected to the first rotating member, the tail being connected to the second rotating member;
wherein the first rotating member rotates with respect to the fore body around a first axis to drive the tail to curl; the second rotating member rotates with respect to the fore body around a second axis to drive the tail to swing left and right; and the first axis is perpendicular to the second axis;
wherein the fore body comprises a frame and a connecting member, the frame has an arc-shaped guiding portion, the connecting member has a guiding recess, and the arc-shaped guiding portion is disposed in the guiding recess; wherein, when the first rotating memberrotates with respect to the fore body around the first axis, the connecting member slides along the arc-shaped guiding portion along with the first rotating member and the second rotating member;
wherein a number of the at least one driving wire is three, each of the plurality of joint members has three through holes, the three driving wires pass through the three through holes of each of the plurality of joint members, one of the three driving wires is connected to the frame to drive the tail to curl, and the othertwo of the three driving wires are connected to the connecting member to drive the tail to swing left and right.

### Claim 2 (depends on 1)

The bionic animal of claim 1, wherein the elastomer has a plurality of positioning portions, each of the plurality of joint members has a portioning recess, and the positioning recess is sleeved on the positioning portion to position the joint member on the elastomer.

### Claim 3 (depends on 1)

The bionic animal of claim 1, wherein a plurality of joints are formed between the plurality of joint members, the elastomer has a plurality of deformable rebound structures, and positions of the plurality of deformable rebound structures correspond to positions of the plurality of joints.

### Claim 4 (depends on 1)

The bionic animal of claim 1, wherein each of the plurality of joint members has two inclined restraining surfaces, and the two inclined restraining surfaces restrain a left and right swing angle of the joint member.

### Claim 5 (depends on 1)

The bionic animal of claim 1, further comprising a plurality of shell members, wherein each of the plurality of shell members has an engaging portion, each of the plurality of joint members has an engaging recess, and the engaging portion engages with the engaging recess to fix the shell member on the joint member.

### Claim 6 (depends on 1)

The bionic animal of claim 1, wherein the elastomer is integrally formed through 3D printing.

### Claim 7 (depends on 1)

The bionic animal of claim 1, wherein a material of the elastomer is thermoplastic polyurethane.
